[Setting up animal model of traumatic pseudoaneurysm: experimentsal and clinical study]
1Wuhan General Hospital of Guangzhou Military Region, People's Liberation Army, Wuhan 430070.
Objective:
To patlern the clinical ruptures of injured arteries.
Methods:
Traumatic methods and microsurgery were employed.
Results:
Experimental model of pseudoaneurysm was made in 72 femoral arteries of 54 Japanese white rabbits, with a successful rate of 95.8%. Using these models, the process and the mechanism for the formation of pseudoaneurysm were studied. The effects of color Doppler's ultrasonic image, CT, MRI and arterial angiography in the diagnosis of pseudoaneurysm were evaluated.
Conclusion:
The indicators for clinical signs of the rupture hemorrhage of pseudoaneurysm were put forward. The methods for balloon dilation to block the blood supply of the carrier artery and control the hemorrhage of operation were set up.
